From 5f02387d745a334a9bce1df61e6193cf110b425f Mon Sep 17 00:00:00 2001 From: Nathan Froyd Date: Wed, 23 Mar 2011 01:56:12 +0000 Subject: [PATCH] refactor emit_*_{after,before}_noloc using common functions refactor emit_*_{after,before}_noloc using common functions * emit-rtl.c (emit_pattern_before_noloc): New function. (emit_insn_before_noloc, emit_jump_insn_before_noloc): Call it. (emit_call_insn_before_noloc, emit_debug_insn_before_noloc): Likewise. (emit_pattern_after_noloc): New function. (emit_insn_after_noloc, emit_jump_insn_after_noloc): Call it. (emit_call_insn_after_noloc, emit_debug_insn_after_noloc): Likewise.
